I hope everyone sits down and reads these reviews about Millie's HVAC. They are complete Liars they are fraudulent they're incompetent and they are negligent. Kamal is a complete rude nasty liar. Do not get these people out for any service you will be sorry I'm telling you. Don't say you weren't warned!

I reside in a condo building. A neighboring unit owner hired Millie's HVAC to replace their HVAC unit. Unfortunately, the wiring for the neighbor's unit apparently was confused with the wiring for my unit. Hence, the electric wiring to my HVAC unit was cut. This may have been an accident, but there was no attempt to notify me of the mistake nor has Millie's HVAC returned numerous phone calls from me as I attempted to ask them to remedy this issue. This is nothing but a 'hit and run' accident with no acknowledgment on the part of Millie's they are at fault. The

Our AC unit went down on the hottest day of the year. Millie's was the only company I could find to come out that day. The unit was beyond repair, and I expected that it would take several days before a new one could be installed. Millie's had the unit replaced by the end of the day, at a fair price. We were very impressed with the service.

Hey Guys. I had my AC go out about a month ago. I called three companies, and Millie's was the first to answer. I canceled the other ones, and Millie's techs showed up in about three hours. They had called and narrowed the time down. Back in the '70's I fixed AC units, so I made a [correct] diagnosis. When the techs arrived, they checked things out and we agreed on a problem, a solution, and a price. They made the repair, the AC cranked, and I was a happy man.
I'd like to stress that the main tech had obviously been doing this for a long time, and the techs were plainly

Called them on a Friday evening when my A/C unit finally went on life support. They sent Mark out within about 2 hours to diagnose the problem and tell me what I knew was coming...I needed a new unit. Big sigh! I live in a high rise condo and due to how my compressor unit was sealed into the exterior wall, they had to send "Jack" out to complete the installation. Jack was billed as a McGuyver who could solve every problem. He delivered. He worked like a dog (with 2 helpers) to get my new unit in, and running. I have never seen someone work so hard. He was pretty entertaining too
